Virtual memory space requirements
The following indicates the user region necessary to run BCM.
• User region under 16 MB: 1,024 KB
• Extended user region over 16 MB
For TSO/E:
– 4,000 KB + (2 x number of volumes) KB
◦
◦ For Batch:
– 4,000 KB + ↑(1.5 x number of volumes)↑ KB
number of volumes: Number of all volumes included in DAD used. When two or more
copy groups are operated, they are sum totals of the number of volumes that each copy
group uses.
The following indicates the user region necessary when linking with Replication Manager. The PREFIX
parameter and DEVN parameter in the formula below are the initialization parameters of the BCM
agent.
• User region under 16 MB: 2,048 KB
• Extended user region over 16 MB
6,000 KB + A KB
+ ↑(512 x number-of-specified-PREFIX-parameters) ÷ 1,024 ↑ KB
+ ↑ (64 x number-of-specified-DEVN-parameters) ÷ 1,024 ↑ KB
A: The larger value of the following: the value of (1.5 x D) and the result of (3 x P)
D: Among the numbers of devices specified for the DEVN parameters, the highest number of
devices.
P: Among the copy groups used by the BCM agent, the highest number of copy pairs in any
group.
The amount of memory required to use BCM Monitor is shown below.
• For a user region of 16 MB or less
2,048 KB
• For an extended user region of 16 MB or more
6,000 KB + (3 number-of-copy-pairs) KB + (C + S) 1 KB
C: Number of copy group parameters specified in the YKMONCG file.
S: Number of action parameters specified in the YKMONCG file.
